New Hubbard Brook hydro and hydropedology papers from the group

Our graduate students and collaborators on Hubbard Brook projects have several new papers now available online. Bourgault, R. R., Ross, D. S., Bailey, S. W., McGuire, K. J., Gannon, J. P., 2017. Redistribution of soil metals and organic carbon via

New paper linking water age and solute dynamics at Hubbard Brook

Paolo Benettin’s paper was just accepted, which was the result of his study abroad visit here in the lab during the fall 2013 and spring 2014.  The manuscript explores water age-dependent transport in estimating weathering-derived solute export.   The model predicts water travel time dynamics

Two new papers on water travel times in catchments

Two new papers are available in Water Resources Research on water travel time estimation in catchments.  Both represent collaborations with colleagues to advance techniques in understanding the transient nature of travel time distributions.  We’re getting closer and closer to answering

New paper about how forests lose nitrogen through shallow groundwater flowpaths

In a paper published in the Proceedings of the National Academy of Sciences, McGuire working with a team from the Hubbard Brook Ecosystem Study found clear evidence of nitrogen loss through denitrification in isolated shallow groundwater patches in a small

Welcome Paolo!

Paolo Benettin, a Ph.D. student from the University of Padova in Italy, arrived last week and will join our lab group for the next 9 months. He will be working on watershed modeling of transport processes and using stable isotope

The launch of isotope hydrology through a beer bottle

Cool blog post from Simple Climate on Willi Dansgaard, the father of isotope paleoclimatology and hydrology.  Check it out: “How a beer bottle helped reveal rapid past climate change” Ok, so the article is mostly about the impact Dansgaard has had on

Installing the liquid sampler on the vario “cube”

The liquid sampler for the IRMS is being installed.  We worked through the installation of the C and N components over the last 2 weeks and we’ve now moved on to water.  Soon we’ll be running water isotopes! We’re also looking

Stable isotope ratio mass spec installation

We’re in the middle of installing our new Isoprime 100 IRMS with Elementar. In a few weeks we’ll be ready to run CHNO isotopes in liquid or solid material. Woowho!

Stuff you should know…mountain-top mining

Mountain-top mining seems to be in the news everywhere these days.  Josh and Chuck, two of my favorite podcast personalities who host “Stuff You Should Know (SYSK),” had a story on mountain-top mining last week called “What is mountaintop removal mining?”
